Term "CJ El"

Term "CJ El"

Term "CJ El"

(OP)
Hello,
Quick question as I'm a mechanical engineer having trouble understanding a drawing.

The drawing is for the detail plan and elevation of a retaining wall, and it keeps noting "CJ El". I'm assuming this references a certain point/elevation, but I'm having trouble finding the original "CJ" on one of over 50 dwgs.
Is the abbreviation "CJ" a common one? What does it stand for?

Thanks in advance!

RE: Term "CJ El"

I normally think control joint for CJ. I could also be construction joint. What is the wall construction?

Is there not a legend of abbreviations?

RE: Term "CJ El"

My first thought when reading your question is "construction joint".  Since it is a retaining wall, I feel certain of this.

The "E" could possibly mean "each". Is the last letter an "I" or an "L"?  Is it a tall wall perhaps over 10 feet?  If L, it could mean "each lift" or each concrete pour.  Tall walls must be placed in multiple steps if it is a tall wall which means multiple construction joints.

RE: Term "CJ El"

Const. or control joint "E1"....is there a reference to a section expressing an E1 joint?  

RE: Term "CJ El"

To follow up on jsdpe, coudl it be Construction Joint ELevation?
